Sounds like that overall the bias ones work better on the trail and are tougher
against puncture and provide a "so - so" ride on the street. (after they have warmed up )
The radials drive very good on the street, you need to drop more pressure to make them perform as equal as the bias but are not so resistant to sidewall damage.
Am I close?
That pirate post was fairly helpful, thanks Dirt Toy Boy!
